FILAMENT SUPPLIER.

Application filed August 1,1923, Serial No. 655,137" Renewed July 18, 1925.

T0 all whom t may concern:

Be it known that we, Surronino Sansa and SEIJI' NIsHTKAwA, subjects of the Emperor of Japan, residents of VTokyo-Fu, Japan, have invented certain new an-duseful invention of Improvements in Filament Suppliers,

Another object of the invention is to mini- Y' mize the knots or frizzles of the silk strand to be formed at the joining points of filaments so that the nature of raw silk is improved.

A The invention comprises ametal or porcelain or any other smooth wire projecting its arm horizontally sidewa-rd at the lower part of the vertical revolving vspindle provided with a'fine holeat its centre to make filaments or a Vsilk strand passthrough it in silk reeling machines of any known type. At the inner end of said projecting arm 'a spiral annulation is formed `a little beneath the lower end of the spindle and continuous to the other end of said spiral annulation a spiral or inclined guide is formed around the lower part of the spindle leaving a littlespace between the latter. The spiral annulation and the spiral or inclined guide is made successively of the same wire to form the main part of the supplier and at the upper end of the guide the wire is fixed to the side ofthe spindle or a revolving sleeve at a point a little above the lower end of the spindle. 'A cocoon, with its filament unloosed and held above', is dropped beside the supplier, and according to the revolution `ofthe latter thef filament is caught at the arm of th-e supplier and A'slidingalong.it is takenvtoward y the centre. After some revolutions of the supplier the taken in part of theV filament is directed substantially `parallel to the spindle by means of the yspiral annulation and spiral or inclined guide and thenr isv adjoined to the other filaments which areV in the course of reeling and the end of" the supplied filament is cut while reeled up together with the other ilaments through the spindle to form a silk strand.

It is already known in filament suppliers to take in the filament of a dropped cocoon by means of horizontally projecting arms,

weak does not attain enough pressure tov stick fast on the running strandunless after the supplied filament is wound several times on the former which gives rise to a notable knot on the strand at the joining point of the filament. According to the present invention the filament when taken into the centre of the supplier does not come in contact with thefrunning nlaments atonce, but the 'taken in part of it being previously direct-ed parallel to the spindle or running strand before it is brought in contact with the otherv filaments by means ofl` the spiral i annulation and the spiral or inclined guide successively formed at nthe inner end of the projecting` arm, and` afterward is adjoined to the other filaments, the pressure of the sup` vplied Afilament on the running filaments is remarkably increased and thereby` immediately sticks fast and is reeled up together with the running filaments without awaiting for being wound several times. Thus' the formation of ljointing knots on the strand is avoided. Furthermorer in those filament suppliers of thel type wherein the other end of the supplied filament is cut by the tension "of the ruiming strand, the nired end of the filament is generally stretched sidewards and at the mom-ent of being cut the end of the filament rebounds oppositely sidewards and being aptto project out of the strand forms knots or frizzles at the ointing points of filaments. Accordingto the present invention the taken in part of the filament being previously brought parallel to the strand by means of the spiral annulation and spiral kor inclined guide' as stated, when said part of the filament is Vcutby th-e tension of the strand it rebounds downward parallel to the strand and as it is rubbed on the running filaments by the revolution of the spiral annulation the frizzled end of the supplied filament becomes adhered lto the strandand the formation of frizzles is also entirely avoided. 5 f. t l

The annexed drawing shows the filament suppliers embodying the present invention. Fig. l is an elevation, partly in section of the filament supplier. Fig. 2 is a plan view 'of the wire forming the essential part of the invention. Figs. 3 and 4 are enlarged views of the supplier showing the action of sup` plying a filament. Fig. 5 is an elevation partly in section of a modified supplier. Referring to Fig. l, a spindle (l) of the silk reeling machine of any known type in conically tapered at its lower end and pro vided with a fine hole at its centre to make a silk strand pass through. The spindle is vertically mounted on an arm of the fame work and is made to revolve by a grooved pulley or any other suitable driving mechanism. A filament supplier (4) made ot metal wire, porcelain or any other smooth wire is arranged at the lower part of the spindle. lt comprises an arm (41) horizontally projecting sidewards with a suitable curvature. At the inner end of said arm (41) a spiral annulation (-42) is formed a little beneath the lower end of the spindle (1). Successive to the other end of the annulation (42) a spiral guide (4.0) is formed around the lower end of the spin` dle (1) with a little space between the latter. Said arm, annulation and guide are successively made of the same wire (4) and the upper end of the guide (44) is bent and fixed to the side of the spindle (1) at a point a little oft the lower end of the latter.

In a modification shown in Fig. 5 an inclined guide (43) is formed with little space around the spindle (1), in place Of the spiral guide (43) in Fig. 1. The spindle (1) in place of being made to revolve as shown in Fig. 1, may be fixed on the frame work as shown in Fig. 5. A sleeve (5) provided with a grooved pulley (3), is rotatably arranged around the spindle (l), and the upper end (44) of the inclined guide (42) is fixed at the side of' said sleeve.

When it is desired to supply a filament to the silk reeling machine a cocoon with its filament unloosed and held above is dropped beside the supplier as shown in dotted lines (o) in Fig. 1. According to the revolution of the arm (41) the filament is caught. and sliding on it is taken toward the centre of the filament. supplier as shown at (b) in Fig. 1. When the supplier further revolves the upper part of taken in filament ascends along the spiral guide (43) (or the inclined guide (43) in case of Fig. 5) while its lower part being sustained at the spiral annulation (42) the taken in part of the filament becomes directed substantially parallel to the axis of the spindle without making contact with other .filaments (d) which are' in the course of reeling as shown in dotted lines (c) in Fig. 3. When the upper end of the taken in filament reaches to the upper end (44) ot the guide it can slide no more along said guide and the supplied filament revolves together with the spindle (l) and the filament suppliers, so that the filanient is twined on the other filaments (el) at the lower end of the spindle (1) as shown at (c) in Fig. 3. The filament being previously stretched parallel to the spindle by the action ot the spiral annulation and guide, presses more intensely on the other filaments (d) in comparison with those filament suppliers hitherto in use, and instantly produces sufficient pressure to stick fast on the running filaments without twining on the latter several times, thus the formation of notable knots at the jointing points of filaments is avoided. After the supplied filament has stuck fast on the other filaments it is reeled up together through the hole of the spindle to form a strand7 and the upper part of the supplied filament is cut by the tension of the ruiming strand. As the supplied filament is previously di* rected parallel to the spindle, the end of the filament rebounds downward as shown in dotted lines (f) in Fig. 4. The supplied filament is reeled up together with other filaments in the course of reeling as sta-ted, the hanging` end (f) of the supplied filament is rubbed on the conical surface of the other filaments (d) by the revolution of the spiral annulation (42) while the former are reeled up as shown at (g) in Fig. 4, and the frizzled end of the supplied filament becomes close-li,7 adhered to the strand. Thus the jointing point of the supplied filament is rendered smooth and inconspicuous and therefore the nature of raw silk to be manufactured is remarkably improved.

`W e claim ln a silk reeling machine., a vertical spindle provided with an axial bore to permit filaments to pass through the same, and a smooth wire including a substantially horizontal arm projecting outwardly from the axis of the spindle, and having its inner end of spiral formation. the spiral portion extending both above and below the lower end of the spindle and surrounding the axis of the latter. the upper part of the spiral portion being spaced from the lower end of the spindle. said spindle including a Sleeve to which the upper part ot the spiral portion of the wire is connected, and means for rotating said sleeve.

In testimony whereof we have affixed our si gnatnres.
